k3s-homelab

part of my homelab on an intel nuc running debian

Motivation

k3s is lightweight enough, for home usage. i have more than a few containers running, and compose takes time to setup as well.

Batteries included

this will install k3s with ansible on debian.

included components:

• k3s
• metallb
• traefik
• prometheus
• grafana
• elasticsearch
• nfs-client-provisioner (nfs server must exist, otherwise remove the chart)

I am using a public domain for the traefik lb and i am getting letsencrypt wildcard certificates with dns-01 challenge. Domain is hosted on ovh.

this is tied to my setup, but should be generic enough to use it right away. some changes in the helm values files may be required for the traefik config if you want to use self signed certs, though.

requirements:

• ansible
• rsync (i am using the synchronize module for faster copy speed n ansible)
• ssh-key auth, this will not work with password auth

getting started

clone or edit the inventory and run it on a debian server. may run without problems on ubuntu, but haven't tested.

after that run

ansible-playbook -i inventories/example-inventory install.yml

grafana login is: grafana.your-domain

user: admin

password: from your inventory

kibana login is: kibana.your-domain

user: elastic

password: kubectl -n logging get secret elasticsearch-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode

traefik login is: traefik.your-domain

basic auth is from your inventory
